I killed all the Grimm Monster in the 601st Level and collected their stuff before I moved to the next level, where I did the same.
Now that I have reached the Adamantine levels, releasing kindles is not enough, I have to be fast to kill all the Admantines within three seconds before they crush their badge and disappear.
Each Grimm Monster running away is a great loss for me; each of them holds a huge amount of resources that takes me closer to my next Advancement and which I am steadily approaching.
In each level, the quantity of the resources would increase by a few point percentages, and sometimes if I am lucky, I would find some good resources that would increase the quantity by one to two percent.
Though it rarely happens, it happens, which made me very assured that as long as I did not come across a particularly tough opponent that could oust me out of the Tower, I will be able to upgrade my Constitution in Level 11.
